Manual Soldering: See Profile B in Supplement section. Cleaning: These devices are not process sealed. Hand clean locally using alcohol based solution. Standards & Certifications The HB2 pushbuttons have not been tested for UL recognition or CSA certification. These switches are designed for use in a low-voltage, low-current, logic-level circuit. When used as intended in a logic-level circuit, the results do not produce hazardous energy. Supplement Accessories Indicators Touch Tilt PCB Processing D18 www.nkk.com Toggles Series HB2 Rockers Distinctive Characteristics Pushbuttons Quiet actuation combined with crisp tactile feedback suited for broadcast equipment. Full face illumination with choice of red/green or red/yellow bicolor LEDs, as well as simultaneous bicolor illumination which produces amber. D Option of legends on caps or film insert. Keylocks Compact design with short body .669” (17.0mm) from PCB to top of cap and .295” (7.5mm) square cap. Programmable Illuminated PB Subminiature Audio/Video Pushbuttons Rotaries Sliding Twin Crossbar (STC) mechanism provides unequalled logic-level reliability, contact stability, smooth positive detent actuation, and long life. Slides Crimped power terminals ensure secure PCB mounting and prevent dislodging during soldering.
